  Parameters
  [in] | ptr | JSON pointer
  [in] | array_idx | array index
  Returns a new JSON pointer with array_idx appended to ptr Example The example shows the usage of `operator/`. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create a JSON pointer 9 json::json_pointer ptr("/foo"); 10 11 // append a JSON Pointer 12 std::cout << ptr / json::json_pointer("/bar/baz") << '\n'; 13 14 // append a string 15 std::cout << ptr / "fob" << '\n'; 16 17 // append an array index 18 std::cout << ptr / 42 << std::endl; 19 } Output (play with this example online):
      "/foo/bar/baz"
      "/foo/fob"
      "/foo/42"
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/json_pointer__operator_add_binary.cpp -o json_pointer__operator_add_binary
Complexity Linear in the length of ptr. See also operator/=(std::size_t) to append an array index Since version 3.6.0 Definition at line 11235 of file json.hpp.
